when installing these do you replace the primary o2 sensor with it or do you put it further down the exhaust, i bought the car with a test pipe and i can only see one o2 sensor, not 2 like other ppl have, i'm taking it to the shop to get it on a ramp to fit this and was just wondering

 

how are you even driving the car only using 1 o2 sensor?

you would be running rice as expletive....actually more than stock because of that. get a High flow cat that has the secondary o2 bung and go at it that way....then worry about where to put the 02 sensor.

 

see i wondered that myself but ti got the cat in the trunk when i bought it and it has no bung for a O2 sensor, as i understand it the secondery o2 is only fro making sure the primary is working right?

 

you have an OBD2 car

your primary is pre cat. the secondary is post cat. Party to verify, if you want to think of it that way, but to make sure the car isnt running too rich or too lean, verify the cat is doing its job

 

the car is obdII, 97 2.2, i only have the one o2 sensor, no cel's but it does run rich, i can smell it and the exhaust tip is black as hell. i've got an s300 going in soon which means i'll be obdI obviously so i was wondering whether i could just replace the standard o2 sensor with my wideband LC-1

 

you wont run proper less you get the boomslang (or insert prefered OBD conversion harness)

you should be throwing a code if your secondary o2 is not hooked up

 

if your going to hondata s300, you can run with the wide band alone without the factory o2 sensor, and wire in the wide band signal out to the s300 and use that to tune and operate with that

 

that was what i wanted to do, i didnt know i i would throw a code if i removed the stock o2 sensor and replaced it with a wideband hooked up to the s300

 

if you run the s300, its practically a standalone, so you`ll be find.. you can set your own parameters with that

 

you can disable readings for the the narrowband o2 signal in hondata if your wideband does not also simulate a narrowband output

im just trying to figure out if you really know what a wideband O2 sensor is for? you know its mainly for tuning right?

 

yeah i know its for tuning, that why i paid nearly $200 for it, i just wanted to know could i just take out the stock narrowband sensor out and replace it with the bosch wideband sensor, using the stock sensor boss already there, i assume the stock ecu used the sensor for sumthing, but i got a p28 now

 

buying just the wideband sensor isnt going to do anything for you if its not hooked up to something for data aquisition. i have no idea if hondata can get the necessary info from replacing the stock o2 with a wideband.

 

I agree, are you heavily modified? If not i think its a waste of money. It will only give you a reading of you afr's thats it . You need to have both of your o2 sensors , to throw the wideband sensor in the mix you need to weld another bung into the header collector if youre all motor or into the downpipe of the exhaust.

 

Is there any consensus on which wide-band is the best for Preludes?

 

the aem one is pretty nice.

i run the zeitronix myself and i have had absolutely no problems with it. I like all the extra features it comes with as well.

 

i run aem, and used it for my ems

 

yes bluelude i know you cant use a wideband lambda on its own, what the hell would be the sense in putting a wideband sensor in the place of a $40 stock sensor. i have the wideband and the controller, i know i can use hondata to trace my a/f, my question was since i'm now obdI with my p28 can i use the stock o2 sensor boss to install my wideband sensor, i.e. remove my stock sensor. and no i'm not heavily modified, i will be eventually and starting with a good tuning system is not a bad place to start in my opinion if your going where i plan to go with my setup

 

u want to place the wideband before the cat. Most people, including myself, have an extra bung welded onto the collector of the header.

 

the only o2 sensor i can see on the car is before the testpipe, what do you think about using the original sensor boss for the new wideband sensor

 

u need that sensor for part throttle reasons. If you dont have that sensor hooked up during tuning, you have run open loop all the time. Meaning that you better have one damn good tune on there or during daily driving, its going to suck driving and your going to get bad gas mileage. Under part throttle, closed loop, the primary o2 sensor "assists" in fuel compensation. Without it, you will be running straight off the map.

 

ok, thanku, was thinking that the 0-1 volt output from the controller could have been used for closed while the 0-5v linear could have been used for open loop but i suppose things are never that easy

 

what kit do you have?

 

lc-1

 

the innovative one?

thats the one with the big *** control unit? Damnit i hate that thing.
